Configuring Port Group Monitor
Each line card or module has a predefined set of ports that shares the same backplane bandwidth which
is called port groups. The port group monitor feature helps to monitor the spine bandwidth utilization.
An alarm syslog is generated so that you can provision the ports evenly across port groups to manage
the oversubscription better.
When the port group monitor feature is enabled and you specify a policy that consists of a polling
interval in seconds and raising and falling thresholds in percentages, then port group monitor generates
a syslog if the port group traffic goes above the specified percentage of the maximum supported
bandwidth for that port group (for rx and for tx) and generates another syslog if the value falls below the
specified threshold.
